Getting the best results from Agent mode

Start complex tasks in Plan mode so the agent outlines its approach before writing code. Be specific in your prompts: "Add Google OAuth login to the /api/auth routes using NextAuth.js" produces better results than "add login." Use @-mentions to point the agent at specific files, documentation, or URLs for reference.
